Preparations for our fourth annual MobileBeat conference are speeding along. Today, we’re announcing our thirdround of speakers for the event: Rich Miner, partner at Google Ventures; Tim Schaaff, president of Sony Network Entertainment; Laura Chambers, senior director of PayPal Mobile; Omar Green, director of strategic mobile initiatives at Intuit; and Humphrey Chen, executive director of new technologies development at Verizon Wireless. You can find all of our current speakers here.

MobileBeat 2011 is taking place on July 12 – 13 at the Palace Hotel in San Francisco. We’re convening the brightest minds from across all sectors of the industry to explore who will win in what we’re calling “the 4G Nirvana.”

4G mobile networks have been talked about for some time, but this year they’re finally becoming readily available in the US. Verizon launched its LTE 4G network last December, AT&T is planning to get its LTE network up over the summer, and T-Mobile is steadily pushing up the speeds of its network into 4G territory. And let’s not forget that Sprint has had its 4G network up and running for years.

We’re betting that the plethora of 4G offerings will drive the mobile industry through an even more radical transformation: Joined with faster mobile chips, new operating systems and tablets, the promise of full mobile computing is now a reality.

Rich Miner has over 25 years of experience growing businesses with innovative communications and interface-intensive applications. Rich came to Google through the acquisition of Android, a mobile platforms company that he co-founded. During his early years at Google, he helped lead the development of the Android platform and ecosystem. Prior to Android, Rich was a Vice President at Orange, where he led R&D activities in North America and was an original principal at Orange Ventures when it was founded.
